A WARD OF THE LYELL MEDAL. 



In presenting the Lyell Medal to Mr. John Edward Mark, 

 F.R.S., the President addressed him as follows : — 



Mr. Mare, — 



From 1876 onwards you have contributed fourteen papers to our 

 Journal, most of them on the Geology of the Lake District and its 

 borders, but two being on Welsh and two on European geology. 

 Of these one may specially note those on the pre-Devonian Rocks of 

 Bohemia, on the Stockdale Shales (written in co-operation with our 

 lamented friend Nicholson), on the Shap Granite and its Associated 

 Rocks (jointly with Mr. Harker), and on Limestone-knolls. 



These papers that you have given us are enough to prove your 

 power as an observer and a reasoner both in the field and at home ; 

 but you have also contributed much to the Geological Magazine, 

 often in association with other workers, and I may remark that the 

 frequent coupling of your name with other names shows how your 

 aid is valued and how well you can work with others. Nor is this 

 all : other journals have been enriched by your pen, and you have 

 added the following books to the literature of Geology : — ' The 

 Classification of the Cambrian and Silurian Rocks,' ' The Principles 

 of Stratigraphical Geology,' and ' The Scientific Study of Scenery.' 



Undoubtedly your long continuous service on the Council (from 

 1885 to 1899) has alone hindered us from thus acknowledging the 

 value of your work until now. 



The award of the Lyell Medal may bring an additional pleasure 

 to you in that it has been given to Nicholson, with whom you 

 have so often worked, and to Hughes, whom you have so greatly 

 assisted in the teaching of geology at Cambridge. 



We are proud to add your name to the roll of Lyell Medallists. 



Mr. Marr, in reply, said : — 

 Mr. President, — 



In thanking the Council for the very gratifying and unexpected 

 honour which they have conferred upon me, I feel that they must 

 have been influenced in their choice by personal considerations, 

 as I have been so long among them. The Founder of the Medal 

 stated that the recipient must have ' deserved well of the science,' 

 which in the present case could only be so in that I have tried to
